Subject: [PATCH 2/2] ARM: mx5/mx51_babbage: Use gpio_request_one when possible
Date: Wed, 27 Apr 2011 21:44:32 -0300	[thread overview]
Message-ID: <1303951472-22234-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1303951472-22234-1-git-send-email-festevam@gmail.com>

Instead of using gpio_request followed by gpio_direction_output use gpio_request_one.
